Not sure if this is a bad idea but since our m340i does not include fog lights, and I really like the close range flood they usually provide in all my previous vehicles, I was wondering if we could code the cornering lights to be always on at night as an alternative.
Thoughts?

I happen to know @dmnc02 is the undisputed expert at light pattern coding. His inbox is full though .
If anyone knows how to reach out…

Not exactly what Im after, but I found something interesting and I can confirm it works:
Normally the cornering lights will turn on ONLY if the low beams are active. Highbeam active will not allow the cornering lights to switch on during a turn etc. But you can change this behaviour so that they work ALSO if highbeams are on: change C_CLC_HIGHBEAM_DIS from DISABLE (0x01) to ENABLE (0x00) Note: I think these tags are backwards in bimmercode to avoid confusion in the interface. 0x00 is usually enable. This is to avoid a double negative presumably LOL. Just select 0x00 regardless. |

Did you ever found a way to code this?

I think I found a clue, still finding it out for my self but I am getting close for FLE. But some cars have LHM instead of FLE. Anyway If you have FLE See post #29 of this thread: https://f30.bimmerpost.com/forums/sh....php?t=1304926 If you have LHM https://f30.bimmerpost.com/forums/sh....php?t=1213278 |

Yes!
I think cracked the code of the FLE module. It's actually the same as the LHM module. If the Lightswitch is in A, most of the 'states' the system can be in are defined in the LmmA folder of the FLE ecu. In the LmmB folder are the simpler modes a light can be in. Step 1 is to define the LM_ID & LM_NAME values using lookup table. By doing this we know which module in the headlight is controlled by a specific function. In my case I get the following values 1. LB1 (Low beam 1) 2. LB2 (Low beam 2) 3. HB1 (High beam) 4. DLR1 (DRL angel eyes) 5. N/A 6. AZL (Eyebrow) 7. CL1 (Cornering Light module) If we then look at the FDL for the DRL mode is you can see that the 4th byte is 07 and 6th byte is 04 Code:
DRL_Idx: F045Wert_F048_2G [03 03 03 07 03 04 03] have intensity 100% but the only difference is the ErrorImpact. If there is a error in case of 07, this module gets deactivated while for 04, it get ignored. So output wise it is the same. So byte 4 is the DRL and byte 6 is the eyebrow. So in case the DRL is active either by Automatic determination or the light switch in that position, both the eyebrow & the rings are activated with 100% intensity. If I wanted for example to activate the High Beam and Corner Light I should change the 3rd and 7th byte to a LmmIdx rule that has intensity that is not 0% for example to 04 aswell. See here my sheet which is still WIP but might be useful for understanding Now I don't know if G20 has 7 bytes or more as when I was searching for information I saw the old module had 10 bytes. And I can think that higher series have more advanced lights than the quite simple adaptive lights used in my X1. Also note: I didn't yet test it on my car. If someone is willing to send me a G20 NCD I can take a look if this theory / mapping looks the same for an G20. Last edited by mrpingu; 04-14-2023 at 04:14 PM.. |

Send me the NCD of your light module and I can probably calculate the values.

I however found out the following. There are 17 LM names and made this table: The modes, like in the old module are gone, atleast the references but I expect the table to work somewhat the same. If you look at the LMM1_data, there are repeating 00, 00, 00 |
